HARMONTOWN, Miss. � Authorities say a University of Mississippi student was recorded on surveillance video leaving a bar alone hours before she was found shot to death.

The city of Oxford released the video showing 21-year-old Alexandria �Ally� Kostial alive hours before deputies found her body about 30 miles (48 kilometers) from university grounds. It shows Kostial hugging someone and leaving the bar at about 11:52 p.m. She�s picked up minutes later by a grey van.

Kostial�s roommate said Kostial arrived home around midnight. It�s unclear what happened between then and when her body was found in Harmontown that morning.

The Lafayette County Sheriff�s Department told reporters Wednesday that a preliminary autopsy determined Kostial died of gunshot wounds. Classmate Brandon A. Theesfeld, of Texas, has been charged with murder in her death.
